Find the equation of the line (in slope intercept form) with xx-intercept (4.5,0) and yy-intercept (0,-5.4).

Hello:

let the equation : y = ax+b

xx-intercept (4.5,0) : 0 = a (4.5) + b ... (1)

yy-intercept (0,-5.4).: - 5.4 = a (0) + b ... (2)

by (2) : b = - 5.4

subsct in (1) : 4.5a - 5.4 = 0

a = 5.4/4.5

a = 54/45

a = 6/5

the equation of the line (in slope intercept form) is : y = (6/5) x - 5.4
